"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"We had converted our half bath into a full bathroom. Bridgestone construction offered accurate timelines, competitive pricing and committed people to complete the work. They also handled all the paperwork and permitting and followed up with our local inspectors so that the work could be completed on time. They were extremely clear at all the milestones and payments were structured after the work was completed. Their people kept to covid protocols (taking temperatures everyday, masks all the time, daily record of everyone who was working), and worked with very high quality. Jeremiah was a pleasure to work with, He did a great job of minimizing disturbances to us. They were great at adapting to all the various issues that came up to ensure the job was completed on time with high quality."

Customers say: True professional

"H&A MY Design made building our garage an effortless and enjoyable process! From the moment we walked into their incredible 5,000-square-foot showroom, we knew we were in the right hands. The showroom truly is a one-stop shop where we could explore construction materials, finishes, and design ideas all in one place. The team helped us narrow down options that fit both our vision and budget. Their professionalism, attention to detail, and seamless communication were second to none. The construction crew was respectful and clean, completing the job on time without any hassle. I wouldn’t hesitate to recommend them for any home improvement project."

"After several long years of designing and permitting our home remodel during the pandemic, we were searching for a good contractor to build out our remodel and second story addition. Avi and David were wonderful; very thorough in explaining the process, answering all of our questions, and settling on a price that was reasonable and within our budget. During the building process, David was very responsive, available, and receptive to changes and last minute decisions made along the way. The project took longer than anticipated and there were some unexpected setbacks, but David and Avi worked quickly to fix issues and keep the project moving forward. At the end of the project they were very responsible about making sure we were satisfied with every last detail before completing the project. Our new home is beautiful and we're very happy with how it turned out, thanks to David and all the crews at So Cal Builders."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"America Green Builders did an addition/remodel on our property. They came in on time, and on budget. The quality they delivered was exceptional, and they paid close attention to detail. All the workers were very professional, showed up on time and left the workplace clean. The project manager was super responsive and constantly interacted with us on chat. We are extremely happy with the final outcome, the value we got and with America Green Builders. I would work with them again and recommend them to everyone."

"We've been in our Lakewood home over 27 years and finally made the decision to put our "60's kitchen out to pasture. We had three good contractors bid for this project. We were most impressed by Ben of Creative Home Remodeling Group. His enthusiasm, attention to detail and follow-thru remained constant from concept to completion. Ben overperformed and under promised. His crew of company contractor specialists have been with him for years, and their rapport and communication showed in the finished project. He was on site and/or in phone contact with them and us constantly. They finished ahead of time with Ben staying on task through each stage and to final inspection. No reflection on Ben or his company, but us being a first- time user of a contractor's services, we were a little green about the process, the quotation and what to expect. It is often said to add 20% to the bid for unexpected costs. There were two legitimate additions that couldn't be anticipated. They were fully explained and understood. It is important for anyone doing this, to make good notes and keep in mind what the bidder is contracting to provide and what your responsibilities will be. Ben made this clear from the start-nothing hidden. Many items required us to go to the vendor, choose, and to pay directly, outside the bid parameters. These items-specifically: the vinyl flooring, the quartz counter tops and backsplash, sink, faucet and disposal being the main ones. For the most part, only the highest expense (the cabinets) was factored into the quotation. My wife and I would use Ben and Creative Remodel again and recommend him and his Studio City company without reservation"

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

FAQs for addition to existing structure building service projects in Van Nuys, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
